O.J. Simpson held a Super Bowl party in his cell at Lovelock Correctional Center in Nevada, where he’s serving a 33-year sentence for kidnapping and armed robbery. Simpson is one of the few inmates who has his own TV, reports The Post’s Richard Johnson, so his friends crammed into his 80-square-foot cell to watch. “If you have the money, you can buy a TV at the inmate store and put it in your cell,” Simpson’s producer friend Norman Pardo said. There was no shortage of potential guests because he’s so popular. “He’s like the Godfather of the prison now,” Pardo said of the one-time NFL great. Meanwhile, Pardo is hoping to sell a movie, “Unpromotable,” about his efforts to rehabilitate Simpson’s image after he was acquitted of double murder in 1995. “It shows what it’s like to promote the most unpromotable man on the planet,” Pardo said.
